Case report of suicide by inhalation of nitrogen gas

Nitrogen is an inert gas that is a normal constituent of the air that we breathe. It is a suffocating gas that does not support life and that can be a cause of death by the displacement of oxygen in the atmosphere. The majority of deaths associated with nitrogen have occurred in the setting of scuba diving. Although other suffocating gases have been used as a means of committing suicide, the literature contains little information about the use of nitrogen as a suicidal agent. A case of a 50-year-old man who committed suicide using a homemade suicide device and nitrogen gas is presented.     

Residential Community Associations and the American Intergovernmental System

Despite their growth and functional similarity to census-listedgovernments, residential community associations (RCAs) representa little-researched feature of American federalism. This studyemploys survey data from a national sample of RCAs to examinehow these organizations relate to other parts of local governmentsystems. The findings underscore the similarity of RCAs to localgovernment with regard to service provision, intergovernmentalcontracting, and lobbying with other units. Multivariate analysisshows that where RCAs are overlapped by other local units, includingother RCAs, they engage in more government-like actions. Thearticle also seeks to stimulate further research on RCAs byreflecting on measurement issues and the federalism implicationsof the study's findings.

Small‐Group Dynamics,Ideology, and Decision Making on the US Courts of Appeals

There is some evidence that judges who specialize in particular legal areas vote in more ideologically consistent ways than do nonspecialists. Upon replicating those individual results across multiple legal areas in the US courts of appeals, we assess how this increasing reliance on ideology by specialists affects decision making by others on a three‐judge panel. We find that judges who serve with a specialist are especially likely to vote in a manner consistent with the ideological position of the specialist with whom they serve. These results suggest that specialization has the potential to facilitate panel effects across numerous legal policy areas.     

Developmental Validation of RSID™-Saliva: A Lateral Flow Immunochromatographic Strip Test for the Forensic Detection of Saliva

Abstract:  Current methods for forensic identification of saliva generally assay for the enzymatic activity of α-amylase, an enzyme long associated with human saliva. Here, we describe the R apid S tain ID entification (RSID™-Saliva), a lateral flow immunochromatographic strip test that uses two antisalivary amylase monoclonal antibodies to detect the presence of salivary amylase, rather than the activity of the enzyme. We demonstrate that RSID™-Saliva is accurate, reproducible, and highly sensitive for human saliva; RSID™-Saliva detects less than 1 μL of saliva. The sensitivity of RSID^TM-Saliva allows investigators to sample a fraction of a questioned stain while retaining the majority for DNA-STR analysis. We demonstrate that RSID™-Saliva identifies saliva from a variety of materials (e.g., cans, bottles, envelopes, and cigarette-butts) and it does not cross-react with blood, semen, urine, or vaginal fluid. RSID™-Saliva is a useful forensic test for determining which evidentiary items contain saliva and thus may yield a DNA profile.     

The role of professional associations in technology transfer

This study analyzes the role of public service professional associations or professional interest groups (PIGs) in municipal government technology transfer. The purpose of the study is to examine the role of professional associations in technology transfer and to suggest a number of policy recommendations to assist these associations and the federal government in promoting innovations as potential solutions to local government problems.     

Automatic forensic face recognition from digital images.

Digital image evidence is now widely available from criminal investigations and surveillance operations, often captured by security and surveillance CCTV. This has resulted in a growing demand from law enforcement agencies for automatic person-recognition based on image data. In forensic science, a fundamental requirement for such automatic face recognition is to evaluate the weight that can justifiably be attached to this recognition evidence in a scientific framework. This paper describes a pilot study carried out by the Forensic Science Service (UK) which explores the use of digital facial images in forensic investigation. For the purpose of the experiment a specific software package was chosen (Image Metrics Optasia). The paper does not describe the techniques used by the software to reach its decision of probabilistic matches to facial images, but accepts the output of the software as though it were a 'black box'. In this way, the paper lays a foundation for how face recognition systems can be compared in a forensic framework. The aim of the paper is to explore how reliably and under what conditions digital facial images can be presented in evidence.
